Conservation genetics and demographic history of the endangered Cape Fear shiner (Notropis mekistocholas).
We examined allelic variation at 22 nuclear-encoded markers (21 microsatellites and one anonymous locus) and mitochondrial (mt)DNA in two geographical samples of the endangered cyprinid fish Notropis mekistocholas (Cape Fear shiner). Genetic diversity was relatively high in comparison to other endangered vertebrates, and there was no evidence of small population effects despite the low abundanc...
متن کاملOntogeny and Allometry of Body Shape in the Blacktail Shiner, Cyprinella venusta
Ontogenetic changes in body shape and its associated allometry were studied in the Blacktail Shiner, Cyprinella venusta, using geometric morphometric methods. We used a single, large sample (n 5 397; 182 males, 215 females), collected in Catahoula Creek, Jourdan River drainage, Hancock County, Mississippi. Ten body landmarks were digitized from each specimen, which yielded partial warp scores t...
متن کاملEffects of Red Shiner (cyprinella Lutrensis) on Red River Pupfish (cyprinodon Rubrofluviatilis )
A proposed desalinization project that would affect the entire upper Red River basin, Oklahoma-Texas, would, if completed, raise the possibility of invasion by red shiner, Cyprinella lutrensis, into stream reaches from which it has been restricted by naturally high salinity. Because introduced red shiners are known to impact native fish communities, we asked if red shiner could have an adverse ...
متن کاملHabitat Associations, Life History, and Diet of the Blackspot Shiner, Notropis atrocaudalis
The ecology of Notropis atrocaudalis (Blackspot Shiner) including habitat associations, population age structure, reproduction, and food habits were examined in two east Texas streams from November 2001 through October 2002. Blackspot Shiner were generally found in relatively shallow, slowowing runs, but exhibited no strong seasonal habitat associations. The population consisted of four age gro...
متن کاملInfluence of water quality and associated contaminants on survival and growth of the endangered Cape Fear shiner (Notropis mekistocholas).
The Cape Fear shiner (Notropis mekistocholas) is a recently described cyprinid species endemic to the Cape Fear River Basin of North Carolina, USA. Only five populations of the fish remain; thus, it is listed as endangered by the U.S. Government. Determining habitat requirements of the Cape Fear shiner, including water quality and physical habitat, is critical to the survival and future restora...
